Application filed June 9.

To @ZZ whom t may concern:

Bc it known that I, CLEMENT Zorrrr, a citizen of the United States, and residentl of West Allis, inthe county of Milwaukee and State of lvisconsin, have `invented new and useful Improvements in Cement-Block Machines, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.'

This invention relates to cement block machines Vand has for vone of its objects to provide a machine adapted to mold cement blocks having core spaces, which blocks may or maynot be formed. with imitation 'stone surfaces.

A further `object of the invention is te improve certain of the prior devices of this character whereby a 'machine may be produced which will be simple in construction, comparatively, inexpensive to manufacture, and more eiicient in use than those which have been heretofore proposed.

With the above and other objects in view which will appear as the description proceeds the invention consists in the novel details of construction and combinations of parts more fully hereinafter disclosed and particularly pointed out inthe appended claims. l

In the accompanying drawings in which like numerals designate like parts in all the views;

Figure 1 is a. side elevational view of a machine made in accordance with the` present invention, all of the parts being shown in their closed positions; Fig. 2 is an And elevational view of thel arts shown in y Fig. 1 as seen from the right of the said figure ;V i .E

Fig. 3 is a central vertical sectional view of the machine, the mold being shown in its open position; and

Fig. 4 is an elevational view of the parts in their positions illustrated in Fig.4 3.

Referring tothe drawings .the numeral 5 indicates a lsuitable frame upon which is supported ,a substantially upright casing 6 of a size andVV shape to correspond withthe size and shape .of the concrete block which is to be marde., The said casing is provided with a movable bottom plate? which is supported uponthe vertically disposed rods whichvpass through suitable guide-ways 9 aty the bottom of the' said easing and are connected together by means of a yoke t0,

1922. Serial No. 566,993.

as will be clear from Fig. 3. yoke 10 is rigidly connected to the trans` versely extending b ar 1 1 which Ais yadapted to move inthe vertical slots 12 'with which the frame 5 is provided,y and :the *endsl of the said bar have rigidly secured to them the vertically extending'members 13, as will be readily apparent. l

The upper. ends o-f vthe members 13 have pivotally secured to them, as at 14, one end of the links 15, the other ends of the said 'links beingpivotally secured, as at 16,

to one end of the leverarms '17 which are carried byfand rigid with the shafts 18 journalled in suitable bearings 19'upon the frame 5. One of the said shafts is pro'- vided with an operatingleverV or handle 20 while the other` of the said Ashafts 18 is provided with a counter-weight 21, vas will be clear from Figs. 1, 2, and 4. The'said shafts are further provided 'with'` the inter# meshing. gear segments 22 whereby motin imparted to one ofthe said shafts by means of the handle 2O may be transmittedto 'the other of said shafts in the well known manner.

Pivotally secured to the movable bottom late 7 as at 23, is a movable mold member 24 provided with a bottom wall 25, an end wall26, and a, pair of side walls 27. The interior surface of the bottom wall 25 may, if desired, be roughened in order to impart a stone-like surface to the finished block, as will'presently appear, and the end wall 26 is provided with an opening 28 adapted to accommodate a core member 29 Vfor thepurpose of hollowingv out the said blocks. One end ofthe said core member projects beyondthe wall 26, as is best shown inFigs. 1 and 3, and in order to accommodate this projecting end the casing 6 is pro'- vided with a slot 30 into which the said Vprol jecting 4endis adapted. to move.

Pivotally are the bell crank members 32, having the substantially horizontal projecting armsj'33 and the substantially vertical arms 34. The said arms34 are provided with a suitable slip jointV 35 whereby they may be extended,

and the free ends thereof are pivotally con-V nected as at `36 to one corner of the movable mold member 24, as will be clear from Figs. 1 andV 4. The arms 33 of the bell crank members are preferably curved at their free ends substantially as shown, andthese Ysaid arms are adapted tobe engaged by i rol-'ler n secured to the casing 6, as at 31,'

T his said i the mold the lever 2O is moved in-a counterclockwise direction, as seen in Fig. 1, which movement causes a partial rotation of the shaft 18 carrying in the said lever, and, through the segmental gear connections 22, a partial rotation of the companion shaft 18 on the opposite side of the machine.

The movements of these said shafts are transmitted through the lever arms 17 and pivot connections 16 to the link members 15,

ad in turn from them through the lpivot connections 14 and vertical extending members 13 to the transverse bar 11, which in I turn moves the yoke 10, as well as the rods 8v and bottom plate 7 upwardly to the positions shown in Figure 3.

The upward movement of the links 15, vertical members 13, and pivots 14 brings the rollers 37 into contact with the arms 33 of the bell crank members 32 causing the -latter to move about their pivots 31 and swing the arms 34 thereof in a counterclockwise direction, as seen in Figure 1, to the positions illustrated in Figure 4. This causes the mold member 24 to swing about 4its pivot 23, as will be readily apparent, so

that its normally horizontal wall 25 assumes a vertical position, while the wall 26 assumes a horizontal position, as shown in Figs. 3 and 4. .Wlhen in these positions the core. member 29 may be readily removed from the block 40 and the latter itself may be then readily slipped out of the open side ofthe mold, to their initial positions illustrated in Fig.

71 whereupon the operation may be repeated.

Itis obvious that those skilled in the art may vary the details of construction as well as the arrangement of parts without departing from the spirit of the invention and `therefore it is not wished to be limited to the above disclosure except as may be required by the claims.

That is claimed is:

l. A, machine of the class described comprising a casing; a mold supporting member within said casing; amold member pivotally secured to said supporting member; and means for moving said mold and supporting members out of said casingand simultaneously swinging the former about its pivot. i

2'. A machine of the class described comprising a casing; a movable mold support-l I The parts are then returned.

ing member within said casing; a mold member pivotally secured to said supporting member; means for moving said mold and supporting members out of said casing; and means actuated by said last named means for swinging said mold member about its pivot as it emerges from said casing.

3. In a machine for making hollow blocks Vfrom plastic materialthe combination with a casing and a slidable plate member therein, of a mold member pivotally secured to said plate member and adapted to receive and hold a core; means comprising levers pivoted to said casing and mold member for swinging the latter about it-s pivot; and means for moving said plate member out of 'said casing, said last named means also engaging said levers to cause the swinging movements of said mold member.

4. In a machine for making hollow blocks from plastic material the combination with a casing and a slidable plate member therein. of a mold member pivotally secured to said plate member and adapted to receive and hold a core; means comprising levers pivcted to said casing and mold member for swinging the` latter about its pivot; and means including an oscillating shaft and link connections for moving said plate member out of said casing, said link connections also engaging said levers to cause the swinging movements of said mold member.

5. An apparatus of the class Ydescribed comprising a frame; a casing mounted on said frame; a movable plate within said casing; a mold memberY pivotally secured to said plate; connections between said casing and mold member, comprising bell-crank levers pivoted on said casing and connected to said mold member, for swinging the latter about its pivot; a plurality of oscillating shafts carried by said frame; link connections between said shafts and plate for moving the latter into and out of said casing; and means carried by said link connections for engaging one arm of said bell-crank levers to swing said moldy member.

6.
